The purpose of this study is to assess the effects of outlook project for olive flounder, from the view point of price stabilization, market efficiency, and causality of the prices in different distribution channels. Analytical results show that the volatility of producer price of olive flounder has been significantly mitigated after the implementation of the outlook project. The market efficiency is estimated to be improved after implementing the outlook project although there is an inefficiency on price determination process in some producing regions. The causality test on the producer and wholesale price shows that producing stage leads the wholesale stage in forming the prices. It is found that Jeju leads the flounder price on the size of 500g and 2kg, while Wando leads the price of 1kg size. These estimation result as whole indicate that outlook project for olive flounder has accomplished the intended goals.

This paper aims at efficient determining the economic life of weapon systems. Specifically, the procedure to estimate the life cycle cost at initial acquisition state or at development state using the PRICE model is proposed. The PRICE model is a parametric cost estimation which is widely used in the field of national defense. The model includes the estimation of the cost in life cycle of weapon systems such as research and development, acquisition, operation and support. Using this model, economic life of weapon systems can be determined. Based on an equivalent annual cost (EAC) method which sums the capital recovery with return (CR) and the equivalence cost (EC), the economic life will be calculated. A case study is accomplished to illustrate the proposed procedure.

Recently, Korea's electric industry is in the midst of a period of profound changes in the structure and function, including the introduction of market competition in the generation sector. Korea is in the early stages of market competition, so the market price is chosen by generation costs but will be chosen by bids in future. Therefore, the profits of generators is determined by market pool price and the prospects of pool price are very important for new capacity investment determination of generators and IPPs. This study analyzes hourly marginal costs and LOLP considering basic generation mix and characteristics, develops the relationship of pool price using the above in competition market, and proposes basic direction for profits variation and supply-demand analysis in the electric market in future.

본 연구에서는 매수인이 부동산을 검색할 때, 매수인의 다양한 성향을 고려할 수 있는 새로운 검색 시스템을 제안한다. 이를 위해 부동산 가격에 영향을 미치는 요인들을 분석한 뒤, 지역요인 및 개별요인으로 분류하였다. 다요소 의사결정(Multi-attribute Decision Making) 알고리즘을 통해 매수인이 입력한 검색조건을 분석하여 가중치를 부여하고, 부동산 후보지간 엔트로피 척도를 통해 최적의 부동산 후보지를 도출하도록 설계하였다. 본 검색 시스템의 효용성을 평가하기 위해 부산지역의 실제 부동산 정보를 이용하여 실험을 진행하였다. 실험결과, 본 다속성 통합 검색 시스템은 매수 아파트 검색 시 지역분석과 개별분석을 용이하게 해 주었다. 또한 한번 검색으로 여러 지역의 부동산 후보들을 비교분석함으로써 매수인의 탐색비용을 절감시킬 수 있었다.

정부, 지방자치단체 및 기타 공공기관 등이 필요로 하는 각종 시설공사, 물품, 용역 등의 조달은 국가예산을 사용하여 집행되고 있다. 우리나라에서는 국가의 예산을 효율적으로 집행하기 위하여 "국가를 당사자로 하는 계약에 관한 법률" 시행령 제9조 제1항 제2조에서 예정가격의 결정기준 중 원가계산에 의한 가격에 관하여 규정하고 있고, 이를 근거로 사업목적에 따라 소관부서별로 각기 원가계산에 의한 예정가격의 결정을 위한 대가기준을 가지고 있다. 본 연구는 기술용역의 대가기준에 관한 고찰을 통하여 투명성을 확보할 수 있는 용역비 산출방법을 도출하여 공공기관이 보다 합리적이고 효율적인 예산집행을 할 수 있도록 현실적인 개선방안을 제시하는데 그 목적이 있다.

Competitive bidding in construction is concerned with contractors making strategic decisions in respect of determination of bid price if contractors opt to bid. This study presents a strategy model for deciding optimum tender price with reflecting appropriate profit in competitive bidding using Bayesian regression analysis (BRA). The purpose of the developed model is to help contractors to secure suitable profitability by predicting the actual profit based on key variables. They may affect construction cost at bidding phase, ultimately which help contractors to secure high quality output. The model was tested empirically by application to a bidding dataset collected from a large South Korea contractor. BRA allows contractors to estimate more accurate actual profit by reflecting not only objective information but also subjective experiences and judgments. Consequently, the model can contribute to improvement of decision-making process for setting an optimum tender price.

A joint economic ordering problem between supplier and customer has been formulated where a supplier has to pay the freight cost which follows the principle of economy of scale. An algorithm is given to determine order size and price simultaneously which give gains to both parties. A scenario is presented within which both parties come to a mutual agreement on the revised order size and price by utilizing quantity discount schedule.

대부분의 노선선정에 있어서 GSIS의 적용은 노선선정시 고려되는 토지이용, 토공량, 지가등 몇 가지의 기본자료를 선택하여 데이터베이스를 구축하고 구축한 데이터를 분석하여 노선선정 방안을 제시하고 있다. 그러나 이러한 방안은 노선선정시 고려되는 다중인자들에 대한 복합적인 고려가 미미한 단계라고 할 수 있다. 이러한 문제를 해결하기 위하여 GSIS를 이용하여 최적노선 선정시 다중의사 결정 지원 및 노선선정 절차의 표준화를 시도하여야 한다. 따라서, 본 연구에서는 도로의 최적 노선선정시 AHP기법을 이용하여 다중인자의 정량화를 시도함으로서 노선선정에 이용되는 자료가 효율적으로 제공되어 최적의 노선선정이 되도록 하였다. AHP기법을 적용한 결과 종래의 노선선정시 다중인자들의 경중률을 임의로 적용하던 것보다 합리적으로 최적노선을 선정할 수 있었다.

The perceived quality is a concept considered from the consumer's perspective. So it is differ from the objective determination of product quality. Thus the consumer perception of quality is a subjective judgement of an individual and an overall feeling on the characteristics which includes the product's reliability, performance and so on. In terms of product perception, consumers utilize the product cues in evaluating the product's quality before the purchase and the cues reflecting the quality can be classifisied into intrinsic and extrinsic ones. When the quality perception is limited to the purchase situation, purchase decision dependent on surrogate indicators such as price, are inclined to increase due to the lack of information. Therefore in this study the perceived quality of apparel is controled to the purchase situation in order to examine the consumer's reaction to the price cues and for the convenience of the exploratory investigation. As a result of the empirical study, consumers show differences in quality and value perceptions to the product with the same price depending on the perception whether the price is high or low. The apparel quality evaluation process goes through the steps of "product attributes - perceived quality - perceived value - purchase intention".

This research objective is to determine the optimal price break points for n­block tariff, because comparing non­linear pricing with uniform pricing on the basis of profit, n­block tariff outperforms two­part tariff, all unit discount price schedule, and uniform pricing. Although the merits of non­linear pricing are well documented, the attempt to practice the non-linear pricing in medical service sector has been relatively rare. The determination of the parameters under n­block tariff is the interesting decision making agenda for marketers. Under n­block tariff, the marketers should decide the optimal price break points and the optimal marginal price for each price zone. The results can be summarized as follows: The researchers found that mixture model can be the feasible methodology for determining the optimal number of n­block tariff and identifying the optimal segmentation criteria. We demonstrate the feasibility and the superiority of the mixture model by applying it to the database of medical examination. The results appear that the number of patients per month can be the optimal segmentation variable. And 6­block tariff is the optimal price break for this medical service.
